The 147.075 (+) repeater has a NEW HOME!
Saturday, April 9th, a newly delivered Motorola Quantar repeater
was installed. It is connected to a brand-new antenna located 450 feet
above ground, which was installed a week prior. It's new home is
a 1500 ft broadcast tower located on Sharp's Ridge in North
Knoxville. The new location is just North of downtown
Knoxville. This location is perfect for
Emergency use in the urban areas of the
city of Knoxville,
while other larger scale coverage
machines might be needed for larger-scale regional emergency communications.
The 147.075 repeater shares the building with several high-powered TV
transmitters, WUOT-FM, and several public safety systems. Emergency
power is also available. The photo above shows the new Quantar repeater
at the bottom of the repeater cabinet. It shares the cabinet with
another Quantar UHF repeater in commercial service.

History of the 147.075
Shaver, K4HXD (now SK), originally put the repeater on the air in
1982. It was placed in service at
a the residence of "Doc" Gilmore, WA4MCX (now SK), who lived on top of
Beaver Ridge in North Knox County. It was one of only three
autopatch repeaters when placed in service, and remained an open
autopatch repeater after the other repeaters autopatches
Tim Berry purchased the repeater from George
in 1986. He moved the repeater to Black Oak Ridge at the residence of
Walter Taylor, father of Greg, N4KAC. It remained at Mr.
Taylor's home until 1992. Tim relocated the repeater to the
WUOT-FM Auxiliary transmitter site on the West side of Sharp's ridge
shortly after Tim became the new Chief Engineer of WUOT-FM Radio in
1990. This repeater remained there for several years, while Tim
continued his work there. 147.075 was relocated to a 300 ft tower when
he was appointed Chief Engineer of WIVK-FM and it's sister stations In
January 1998. It served there until April 2022 when it was upgraded to
a Motorola Quantar and relocated to it's new
The repeater was moved to its present
location on April 9, 2022. At this location, it is in a perfect spot for a repeater
due to it's relative close-in location and emergency backup power system.
